It includes a large image library (high-resolution satellite images and ground truth road network maps) covering an area of about 24 square kilometers around the city centers of forty cities in six countries (satellite images are from Google with a resolution of 60 cm/pixel, and road network images are from OSM). The dataset includes:

• A training set of 25 cities and a test set of 15 other cities
